Abstract
A cantilever of cantilever boring machine is composed of an inner arm and an outer arm. The inner arm is installed in the outer arm. An expansion oil cylinder is installed between the inner arm and the outer arm. The upper part of outer arm is provided with a protecting plate. The two sides of outer arm are installed with a supporting body with a back end connected with a rotary disc. A lifting oil cylinder is also provided between the supporting body and the rotary disc. The front end of external arm is provided with a spray device. The novel cantilever according to the utility model can extend and swing so the cutting is more flexible. The outer arm is strengthened and the bearing capacity is bigger. The water mist is sprayed so that the functions of dust elimination and spark generation prevention. The protecting plate installed at the upper part of cantilever protects the cantilever from damaged by the fallen rock.
Description
Technical field
The utility model relates to a kind of boom-type roadheader, specifically a kind of cantilever of boom-type roadheader.
Technical background
Boom-type roadheader is a kind of collection cutting, load, transhipment rock ballasts etc. are in the efficient heading equipment of one, be widely used in traffic, the tunnel, fields such as mining, compare with large-scale development machine, there is volume little, lightweight characteristics, in being applicable to, the small-size coal mine operation, improve the mechanization level, development machine often needs the different section of swing cantilever cutting in operation, at geological conditions environment complicated and changeable, its load fluctuation, machine impacts and shakes all very big, also often is in overload, existing development machine cantilever intensity is little, supporting capacity is low, and is fragile, influenced normal operation.
Summary of the invention
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and provides a kind of supporting capacity big, the cantilever of robust boom-type roadheader.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: a kind of cantilever of boom-type roadheader, form by inner arm and outer arm, inner arm is arranged in the outer arm, between inner arm and outer arm, be provided with telescopic oil cylinder, the top of outer arm is provided with backplate, and both sides are provided with the supporter that the rear end is connected with rotary disk, also is provided with hoist cylinder between supporter and the rotary disk.
The utility model, described outer arm front end is provided with spray equipment, and ejection water smoke in cutting plays depositing dust and the purpose that prevents to produce spark.
The utility model; heading end is installed in inner arm one end; inner arm is arranged in the outer arm; inner arm slides in outer arm under the effect of telescopic oil cylinder, can finish creeping into of cutterhead, can control cantilever up and down or swing by hoist cylinder and rotary disk; the needs that adapt to different section; the supporter that the outer wall both sides are provided with can effectively be reinforced cantilever, increases cantilever and can bear lateral force at work, and the protection cantilever is not lost.
The beneficial effects of the utility model are:
1, the scalable and swing of cantilever makes cut more flexible.
2, strengthened outer arm, supporting capacity is bigger.
3, spray water mist, the effect that has depositing dust and prevent to produce spark.
4, the backplate protection cantilever of cantilever top setting is not injured by a crashing object by falling rocks.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Mark among the figure: 1, inner arm, 2, outer arm, 3, backplate, 4, supporter, 5, rotary disk, 6, hoist cylinder, 7, telescopic oil cylinder, 8, spray equipment.
The specific embodiment
A kind of cantilever of boom-type roadheader, form by inner arm 1 and outer arm 2, the both sides of outer arm 2 are provided with the supporter 4 of reinforcing cantilever, supporter 4 rear ends are connected with rotary disk 5 with bearing, and and rotary disk 5 between hoist cylinder 6 is set, the control cantilever swings up and down, and follow rotary disk 5 left rotation and right rotation, inner arm 1 is arranged in the outer arm 2, is provided with telescopic oil cylinder 7 between inner arm 1 and outer arm 2, slides in outer arm 2 at inner arm 1 under the effect of telescopic oil cylinder 7, reach flexible purpose, above outer arm 2, also be provided with backplate 3, can with in, outer arm 1,2 interface sections that connect and the power section of heading end cover up, and avoid being smashed.
Described outer arm 2 front ends are provided with spray equipment 8, and ejection water smoke in cutting plays depositing dust and the purpose that prevents to produce spark.
